Creating Rules for a Device

You must create a rule for a LUN to add persistence to that LUN. You need to create and

edit the rules file /etc/udev/rules.d/10-HP-Local.rules to create a rule for the

LUN. To create a rule for a LUN, complete the steps below:

NOTE: In SUSE 9 distributions, the rules file 10-HP-Local.rules must be located under the

/etc/udev/ directory.

1. Generate a rule for a device using the hp_gen_rules script that came with the

hpudev-cfg package.

For example, generate a rule for the device /sys/block/sda with mylink as the

name of the link and enter the following command:

# hp_gen_rules sda mylink-sda

The following output appears:

Note: Append the following rule to the /etc/udev/rules.d/10-HP-

Local.rules file

BUS="scsi", KERNEL="sd*", PROGRAM=”scsi_id”,
